Location of supplier: treat the supplier's place of business as the determining factor for place of supply under GST.
Location of supplier of goods is not defined in the GST/IGST Acts; it should be treated as the place where the supplier was located immediately before or at the time of supply and before movement of goods. A CBIC flier treats the supplier's place of business as the relevant location, supporting use of the supplier's business location for determining place of supply under Section 10 and inter state rules.

Location of supplier of services determines place of supply under GST-prioritise place of business, fixed establishment, then residence.
Location of the supplier of services determines place of supply under GST/IGST by a hierarchical rule: (a) location of the registered place of business; (b) location of the fixed establishment when supply is made from another place; (c) location of the establishment most directly concerned where multiple establishments are involved; and (d) otherwise the usual place of residence of the supplier.

Location of recipient of services determines place of supply; prioritise registered business, fixed establishment, most concerned establishment, then residence.
The location of the recipient of services is determined hierarchically: (a) the location of the registered place of business where the supply is received; (b) if received at a place other than the registered place, the location of the fixed establishment elsewhere; (c) where received at multiple establishments, the establishment most directly concerned with receipt; and (d) if none of these exist, the usual place of residence of the recipient. The IGST Act contains the same hierarchical definition.

Taxability of gifts expanded to all assessees; assets received without adequate consideration treated as taxable income.

Cost of acquisition rules: cutoff date advanced, altering use of prior fair market value for long-term capital assets.
Amendment to section 55 advances the statutory cut-off date used to compute cost of acquisition and cost of improvement for long-term capital assets: where an asset was acquired before the new cut-off date, its cost of acquisition is to be treated as the asset's value on that cut-off date and cost of improvement is recognised only if incurred after that date, with fair market value at the cut-off date available as the basis. The amendment is effective from 1st April, 2018 and applies to the assessment year 2018-2019 onwards.

Capital gains exemption expanded to include government notified bonds, widening eligible investments for deferring tax on long term gains.

Fair market value deemed consideration for unquoted share transfers, altering capital gains valuation under prescribed rules.

Cost of acquisition tied to stamp duty value for land pooling allotments determining capital gains computation.
Where capital gains arise from transfer of a specified capital asset received under the Andhra Pradesh Capital City Land Pooling Scheme and transferred after two years from the end of the financial year in which possession was handed over, the cost of acquisition shall be deemed to be the stamp duty value of the asset as on the last day of the second financial year after the end of the financial year when possession was handed over; the amendment also defines "stamp duty value."

Cost of acquisition set as deemed full value of consideration for project-share transfers under development agreements, effective 2018-19.
The amendment provides that the cost of acquisition of a share in a project consisting of land or building, given as consideration under specified agreements (for example, joint development agreements), shall be the amount deemed as the full value of consideration under the related provision, subject to the proviso excluding certain capital assets, and applies prospectively from the effective date for subsequent assessment years.

Deemed cost of acquisition: equity received on conversion of preference shares treated as costing the original preference shares.
A new deeming provision treats the cost of acquisition of equity shares received in consideration of a transfer under clause (xb) of section 47 as the cost of the preference shares in relation to which those equity shares are acquired, thereby carrying over the preference share cost for computing capital gains.

Cost of acquisition rule: consolidated-plan unit transfers deemed to carry forward cost from consolidating-plan units, affecting capital gains.
The amendment deems the cost of acquisition of a capital asset comprising unit(s) in a consolidated mutual fund plan to be the cost of acquisition of the corresponding unit(s) in the consolidating plan when the consolidated units were obtained by a specified transfer, thereby fixing the cost basis for capital gains computation.

Cost basis for demerger transfers: previous owner's acquisition cost to determine transferee's cost for share transfers.
Where shares in an Indian company are transferred in a demerger, the transferee's cost of acquisition shall be the cost for which the previous owner acquired those shares, increased by any cost of improvements, by virtue of the Clause 25 amendment; the change takes effect from 1 April 2018 and applies to assessment year 2018-19 onward.

Indexed cost base changed for capital gains computation, altering base-year reference and effective assessment period.
Amendment revises the benchmark year used in the computation of the indexed cost of acquisition by replacing the earlier base-year reference with a more recent base year, with consequential changes to the mode of computation and prospective application to the stated assessment year and subsequent years, thereby altering the use of the Cost Inflation Index in proportionately adjusting cost of acquisition for capital gains.

Capital gains computation: rupee appreciation on redemption of rupee bonds held by non-residents excluded from full value.
Amendment clarifies that for a non-resident holder of a rupee-denominated bond of an Indian company, any gain arising from appreciation of the rupee against a foreign currency at redemption shall be ignored in computing the full value of consideration for capital gains; the change substitutes "held by" for "subscribed by" and operates prospectively from the notified effective date.

Conversion of preference shares into equity not treated as transfer, changing capital gains treatment from assessment year 2018-19.

Capital gains timing under specified development agreements: tax charged when project completion certificate is issued, using stamp duty value.
Section 45 is amended by inserting section 45(5A) to tax capital gains of individuals and HUFs from transfers of land or building under specified agreements in the previous year when the competent authority issues the project completion certificate; the stamp duty value of the assessee's share on that date, increased by any cash consideration, is deemed the full value of consideration. If the assessee transfers the share on or before that certificate date, capital gains are taxable in the year of that transfer and general provisions (excluding section 45(5A)) apply to determine full value. The amendment defines key terms and takes effect from 1 April 2018.

The change takes effect from the fiscal start date and applies to the specified assessment year and subsequent years.

Audit threshold increase for presumptive taxation reduces audit applicability where turnover does not exceed prescribed limit.
A proviso to the tax audit requirement exempts persons who declare profits under the presumptive taxation scheme and whose total sales, turnover or gross receipts do not exceed the revised turnover ceiling, thereby narrowing the class required to obtain an audit when they comply with sub section (1) of the presumptive taxation provision.
